Validation of the DSCOVR Spacecraft Mission Space Weather Solar Wind Products by Paul T. M. Loto'aniu, K. Romich, W. Rowland, S. Codrescu, D. Biesecker, J. Johnson, H. J. Singer, A. Szabo, M. Stevens

“…The DSCOVR observations of the interplanetary magnetic field (IMF), solar wind velocity, density, and temperature were hourly averaged and compared to measurements from NASA's Advanced Composition Explorer (ACE) and Wind spacecraft. Hourly averages, in general, show good correlations between the satellites for the IMF, solar wind velocity Geocentric Solar Ecliptic (GSE) vx‐component, and density. …”
